Letters Patent No. 105,803, dated July 26,1870.

IMPROVEMENT, IN EARTH-CLOSETS- The Schedule referred to in these Letters Patent and making part of the same l'o all persons to whom these presents may come:

Be it known that I, GEORGE BAKER J EWE'r'r, of Salem, of\ the county of Essex and State of Massa-l chusetts, have made a new and useful invention, havingreference to Earth-Closets, and do hereby declare the same'to be fully described in the following specification and represented in the accompanying drawing, of which- Figure l denotes a top view; Y

Figure 2, a front elevation; Figure 3, a rear elevation and Figure 4,-a vertical, central, and longitudinal section of, an earth-closet, provided with my invention.

Such invention. consists, mainly, in the combination of af vibratory chute, and itsoperative mechanism,

with a rotary discharger, and mechanism for operating it, by means of the seat-cover.

In a recent application made'by nie for a patent for an earth-closet, 1 have represented a rotary discharger or movable hod-carrier or supporter, and mechanism for operating them by means of the seat-cover, a stationary chut-e heilig exhibited as employed below the dischargcr. c In my present earth-closet- 1 dispense with the movable bod-carrier, and in the place of thest-ationary chute, I employ a vibratory one, and certain mechanism, as hereinafter explained, or the equivalent thereof,1or bringing it from a vertical position, or about so, into an inclinedposition, as occasion -niay require, that is, during' depression of the `sea-t-cover.

The object of my invention is to advance the chute far enough to effect a proper dispersion-.of the earth Aupon the deposited excrernent, and also to move the chute back out of the way of being soiled by a person while using. the closet.`

An earth-closet providedwith my invention is applicable to stationary vaults oiI hods.

In thc drawing- A denotes the hopper, as arranged within theseatframe B, in the ordinary way, and directly over a cylindrical drum or discharger, C, pivoted at its ends to two standards a a, so as t-o be capable of being freely revolved on its axis.

There is a mouth or opening, l), in the side of the A drum or discharger, and the heads c o of such discharger. are grooved or formed as pulleys or wheels, and Ahave fastened to their peripheries two chains, l d, which are extended from the cover D of the seat, the latten'viz., the seat, not being represented in the drawing. y

From the hopper .an apron, E, of sheet metal, projects and extends partially around the drum O, in manner-as shown in the drawing, such apron being.to.pre-

vent the earth from being prematurely.discharged from the drum while the latter may be in the act of being revolved, for the purpose of dropping its load upon a chute, F, arranged below the drum ordischarger, in manner as represented.

The heads of the rotary dischargers are provided with two other and smaller grooved wheels or pulleys, e e, from whose peripheries chains ff depend to and4 are fastened tothe chute F, at or near the middles of its opposite sides.

This chute, at or near its upper part, is pivot-ed to the standards or supports of the journals of the rotary discharger, so as to enable the chute to move fromthe `position shown in full black lilies to that indicated h dotted lines in iig. 4. 4

From the larger pulleys or wheels of the rotary discharger, other chains 7a t extend down to and are fastened to a bar, g, arranged acrossthe frame, and having, at or near its ends, other chains It h' fastened.

Each of the said chains It h is carried around two guide-pulleys, Aiv t, disposed as represented, and thence is fastened to the seat-cover.

On raising the saidcover, the bar y will be drawn downward, and, by means of the chains k k, will revolve the rotary dischargers, so as to carry its receiving-opening upto the hopper, in orden that the discharger may be filled or supplied with earth therefrom. At the same time the chute F will be allowed to fall down into a vertical position, which it will do.

On depressing the seat-cover, the rotary dischargerwill' be revolved, and the chute will beraised into an inclined position, and will receive the load of the disoharger, and deposit and distributelit upon or over any excrement or urinal matters that.V may havebeen deposited in the .vault or hod by an individual during the period of raising and lowering the s fat-cover.

It will be observed that the lower hal of the chute has numerous holes or perforations made through it, for the better distribution of the earth. i

I claim- The combination of the vibratory chute and its 'operative mechanism with the seat, and the hopper 'or mechanism for dropping the earth upon the chute, as set forth, suoli chute being to operate in mannerand for the purpose as described.

Also, the arrangement and combination of the bar g, with its two sets of chains, It k h h., the seat-cover andthe rotarydisoliarger, arranged with the hopper,

as explained. y Y
